Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a planting part of a transplanter for onions such as onions, corn and other relatively slender vegetable seedlings.

[0002]

[Prior art]

 Conventionally, in order to continuously plant the above-mentioned vegetable seedlings mechanically, the seedlings that have been divided and attached to the tape are continuously fed by a roll-shaped feeder, and while cutting the tape, the seedlings are dropped into grooves in the ridges. It is known that the seedlings are either covered with soil after the treatment, or the seedlings are supplied manually to a conveyor-like seedling feeder and dropped at the planting section to perform the same planting work.

[0003]

[Problems to be solved by the device]

 However, the planting part of the planting device is attached to the rear of the machine, but if you try to attach a plant with a structure that holds seedlings in the planting part and inserts it into the soil like a rice transplanter, the planting part will move up and down. There is a problem in that the drive mechanism has to be provided at the rear of the machine body, which is complicated and tends to increase in size, for opening and closing the claws and the like.

[0004]

[Means for Solving the Problems]

 The planting portion mounting structure of the present invention for solving the above-mentioned problems is configured such that a feeding device 27 for planting seedlings 29 is provided on the traveling machine body 1 that pivotally supports the front wheels 12 and the rear wheels 13, and the feeding device is provided. A planting section 69 for receiving the planted seedlings 29 and planting it in the field is provided below the terminal end of 27, and the swing arm 74 of the planting section 69 is attached to the machine frame 2 side. A pillar 16 for suspending the rear wheel frame 14 is provided upright at the rear end, and a fixed fulcrum 86 for rocking the rocking arm 74 is provided on the pillar 16.

[0005]

The rear end of the swing arm 74 that moves the planting portion 69 up and down is guided to swing by using the fixed fulcrum 86 on the column 16 side as a fixed fulcrum, and the planting portion 69 is guided by the fixed fulcrum 86. Planting operation is performed. Since the drive part of such a swing arm 74 is installed in the space below the rear wheel frame 14, even a device with a complicated and large trajectory can be attached, and the space near the support column is a walking type. It does not hinder the operation of the steering wheel of the vehicle.

It is pivotally supported on both sides of the rear wheel frame 14. The rear wheel frame 14 is composed of a pillar 16 standing on the rear end of the transmission case 4, and a beam 18 formed of a pipe having a hexagonal cross section which is detachably installed in a T shape on the pillar 16 by a frame receiver 17. The rear wheels 13 are pivotally supported on the lower ends of the arms 21. The arms 21 are attached to both ends of the beam 18 via arm receivers 19 so as to be detachable downward.

Reference numeral 22 denotes a handle made up of two pipes attached to the rear left and right positions of the transmission case 4 extending rearward of the center of the machine body through a mounting plate 23, and between the handles 22 the operation of the machine body is performed. A box 24 is attached, and the left and right handles 22 spread to the upper rear part and extend from the rear wheel 13 to the rear position.

A seedling frame 26 having an inverted triangular shape in a rear view is mounted on the front half position of the machine body frame 2, and a seedling feeding device 27 is provided on the upper surface of the seedling frame 26 so as to descend downward toward the rear. Installed, the feeding device 27 is a cassette-shaped seedling feeder that feeds and stocks a seedling feeding device 28 consisting of two rows of left and right conveyors in the lower stage, and a large number of planted seedlings 29 divided into the seedling feeding device 28. It consists of 31.

As shown in FIGS. 1 to 3 and FIGS. 7 and 8, the seedling feeding device 28 is rotatably supported on the front and rear ends of a conveyor frame 32 installed on the seedling stand frame 26 in the front-rear direction. (30) The chain consists of two rows of chain conveyors around which the chain 34 is wound around the sprocket 33, and a number of L-shaped cross-section plates 36 are fixed to the outer circumference of each chain 34 at a constant pitch in the left-right direction. The planted seedlings 29 are housed one by one between the plates 36 and intermittently sent toward the rear end. Reference numeral 25 is a guide bottom plate of the conveyor.

As shown in FIGS. 7 and 8, side plates 37 are provided upright at the left and right ends at the end of the conveyor frame 32, and center plates 38 are provided upright in the center, and the upper ends of the plates 37, 38 are provided. Has a guide shaft 39 supported in the left-right direction, and the upper end of a guide cover 41 is rotatably supported by a sleeve 42 on the guide shaft 39 so as to cover the end of each chain conveyor at a close position. The seedlings 29 are prevented from being discharged irregularly at the end of the conveyor. Elastic rubber or plastic rings 43 are fitted on both sides of the sleeve 42 to restrict the left and right movements of the sleeve 42. The seedling feeding device 28 is driven by intermittently rotating a ratchet wheel 44 axially supported integrally with the sprocket 33 at the end of the conveyor, and the feeding drive is performed by the interlocking wire 46 (see FIGS. 1 and 1). 9 and FIG. 10), and is carried out intermittently in conjunction with the planting operation of the planting section described later.

As shown in FIGS. 4 to 6, the seedling feeder 31 corresponds to the width (seedling length) of the conveyor between the left and right side frames 47 corresponding to the length of each conveyor of the seedling feeding device 28. A shutter 51 is provided at the middle part (between the upper and lower partition plates 48) and the bottom of the seedling frame 49, which is horizontally arranged in the left and right directions and in two steps vertically at the same pitch as the plate 36 on the conveyor side. It is configured to be inserted and removed freely from the side. And between each partition plate 48, the seedling accommodating part 52 corresponding to the plate 36 of the conveyor is formed, each shutter 51 constitutes the bottom part of each seedling accommodating part 52, and the upper shutter 51 forms the seedling accommodating part 52. It plays a role of dividing into upper and lower parts, and when the shutter 51 is overlapped and inserted, two upper and lower accommodating parts are formed. Reference numerals 53 and 54 denote handles for handling, which are attached to the front and rear ends of the seedling frame 49 and the outer end of the shutter 51, respectively. In the example shown in the figure, the shutter 51 is configured so that the upper and lower two stages and the front and rear two can be independently inserted and removed, and the upper shutter 51 is supported by the upper end of the lower partition plate 48 and guided when it is inserted. However, the lower shutter 51 is guided and supported by a rod-shaped shutter guide 56 provided laterally below the side frame 47.

In the seedling feeder 31 according to the above configuration, first, with only the shutter 51 in the lower stage inserted, the roots of the seedlings 29 that have been stocked in each seedling accommodation section 52 are aligned and stored inside, When the lower stage is full, the upper shutter 51 is inserted, and at the same time, the seedlings 29 are stored in the upper storage unit. Next, the seedling feeders 31 are arranged and mounted on the respective conveyors, and the shutter 51 in the lower stage is first pulled out to drop the seedlings in the accommodation section 52 in the lower stage onto the conveyors. When the seedlings 29 on the conveyor are used up by the planting work, the conveyor is stopped immediately before that, the shutter 51 on the upper stage is pulled out, and the seedlings on the upper stage are dropped on the conveyor to perform the next planting work.

As shown in FIG. 4 and FIG. 5, the side frame 47 on the inner end side of each seedling feeder 31 is provided with a mounting member 57 having an angled cross section, and a long hole 58 of the mounting member 57. The bolt 59 protruding from the conveyor 32 is inserted, and the seedling feeding device 31 is removably mounted by a sleeve nut 61 with a knob. It is possible to prepare a large number of the cassette-shaped seedling feeders 31 containing the seedlings 29 in advance, and sequentially replace and attach the cassettes with another cassette as the planting work progresses. The cassette-shaped seedling feeder 31 can be stacked in multiple stages.

Below the end of each conveyor of the seedling feeding device 28, a funnel-shaped hopper 63 for opening seedlings is attached via a mounting plate 62 (see FIG. 7), and is fed from the conveyor. The seedlings 29 that have fallen due to falling are received, and the roots of the seedlings 29 are directed downward so that they can be stored. Since the seedling 29 has a ball formed at the root of the onion, it naturally falls downward due to its own weight, but depending on the situation of the seedling, so that it does not remain in the reverse direction or sideways, the upper opening of the hopper 63 is A guide bar 64 (see FIG. 2 and FIG. 10) is installed in the vertical direction so that the leaf tip side of the seedling 29 comes into contact with the seedling 29 when it falls and the root portion falls first.

Further, a stopper 64 for receiving and temporarily holding the seedlings 29 that have fallen inside is held in the hopper 63 so as to be opened and closed. As shown in FIG. 10, the stopper 64 is composed of an inverted L-shaped plate whose lower end is bent forward, and its upper end is swingably supported by a shaft 66 on the back side of the hopper 63 and A spring 67 is stretched between the side surface of the hopper 63 and the side surface of the hopper 63, and the lower end bent portion is always biased forward so as to openably and closably close the lower opening end 68 of the hopper 63. The seedlings 29 are held in the hopper 63 when the stopper 66 is closed, and when the seedlings 29 are swung rearward and opened, the seedlings fall in the standing posture toward the lower planting portion 69. Then, the stopper 64 is opened / closed in conjunction with the planting raising / lowering operation of the planting section 69 described later.

Next, the structure and operation of the planting part will be described. As shown in FIGS. 9 to 12, the planting part 69 is a hopper-shaped guide 71 having a lower opening 72 and a guide 71. A pair of beak-shaped planting claws 73a, 73b attached to the lower end of the unit 1 so as to be freely opened and closed is provided. The front planting claw 73a is a fixed claw whose upper end is fixed to the guide 71, and the tip of the rearward swing arm 74 is integrally fixed to the fixed claw 73a, and the swing arm 74 has a fixed end. An L-shaped lever 76 is rotatably supported by a shaft 77 at the tip thereof, and a rear planting claw 73b is rotatably and rotatably fixed to the tip of the lever 76 as an opening and closing claw. The opening / closing claw 73b is overlapped with the fixed claw 73a to hold the seedling 29 inside, and has a mechanism for dropping and releasing the seedling downward in the opened state.

On the other hand, a work output shaft 78 that rotates counterclockwise projects from both sides of the rear end of the transmission case 4, and a base end portion of a crank arm 79 is integrally fixed to the output shaft 78. A crank shaft 81 is integrally fixed to the tip of the crank arm 79, and a rear end of the swing arm 74 is rotatably supported by the crank shaft 81. Further, the tangential cam 2 is integrally fixed to the outer end of the crankshaft 81, and when the crank arm 79 is rotationally driven, the base end portion of the swing arm 74 is counterclockwise along the rotation locus 82 of the crankshaft 81. Rotate in the direction. An upward lever 83 is integrally erected on the base end of the swing arm 74, and a guide link 87 is provided between the upper end of the lever 83 and a fixed fulcrum 86 of a bracket 84 projecting toward the support 16 side. Are connected by.

When the base end of the swing arm 74 rotates together with the crank arm 79 by the above mechanism, the upper end of the lever 83 swings along the swing locus 89 of the swing fulcrum 88 of the guide chunk 87. Due to these operations, the tip of the fixed claw 73a of the planting portion 69 operates like a planting locus 91a when the airframe 1 is stopped as shown in FIG. The seedling 29 is received from the hopper 63 by the guide 71, and the planting operation is performed by the planting claw 73 in the lowered position.

A mechanism is provided for swinging the upper end of the lever 76 in the forward direction so that the opening / closing claw 73b can be heard rearward when the planting claw 73 descends during the planting operation. That is, a claw opening / closing guide link (opening / closing link) 92 is axially supported on the outer end of the swinging fulcrum 88 of the guide link 87, and the lower end of the opening / closing link 92 is always elastically attached to the tangential cam 82 described above. A roll 93 circumscribing is rotatably supported. The intermediate portion of the opening / closing link 92 and the upper end of the lever 76 are connected by an opening / closing rod 94 via a rod end 95. When the opening / closing link 92 swings due to the rotation of the tangential cam 82 and the outer contact of the roll 93, The lever 76 swings so that the opening / closing claw 73b pivots back and forth to open and close.

The opening / closing rod 94 is arranged along the swing arm 74 so as not to come into contact with the seedlings after planting, and a bracket installed upright on the swing arm 74 at an intermediate portion thereof. A spring 97 is externally inserted between the spring receiver 90, which is inserted through the boot 96 and is fitted in the front opening / closing rod 94 so that the front-back position can be adjusted. The spring 97 biases the opening / closing link 92 forward and elastically pulls the roll 93 forward always when the tangential cam 82 moves and changes its posture due to the crank rotation of the crankshaft 81. The roll 93 always acts to circumscribe the tangential cam 82. Therefore, the opening / closing posture of the opening / closing claw 73b during the ascending / descending operation is affected by the shape of the tangential cam 82.

In the present embodiment, as shown in FIG. 10, after the planting section 69 moves up and receives the seedling 29 from the hopper, the planting section 69 keeps the closed state until it descends to the field scene, and the planting claw 73 is set to the lower limit. When it is lowered to the vicinity of the position, the opening / closing claw 73b is opened backward to complete the planting with the seedling 29 inserted in the field, and the mechanism is such that the seedling 29 remains open and rises. The shape is also designed to allow such an operation.

Next, the delivery of seedlings from the hopper 63 to the planting section 69 will be described. As shown in FIG. 10, a rod-shaped opening / closing guide 101 for driving the stopper opening / closing is provided on the side of the hopper-shaped guide 71. Is erected vertically, and its upper end is bent so as to incline backward. On the other hand, on the stopper 64 side, an attachment 102 is attached that contacts the rear surface of the upper end of the opening / closing guide 101 and swings the stopper 64 rearward only when the planting portion 69 descends from the upper limit position. When the planting portion 69 rises, the opening / closing guide 101 does not come into contact with the attachment 102 due to its ascending locus, but when it comes down from the upper limit position, the opening guide 68 swings the stopper 64 rearward and the hopper opening 68 Is opened and the seedling 29 inside is dropped in the planting section 69 while standing. When the planting portion 69 descends downward, the stopper 64 is restored to the closed state by the spring 67.

The proximal end portion of the wire 46 for intermittently driving the sprocket 33 in the conveyor of the seedling feeding device 28 is connected to the proximal end portion side of the above-mentioned guide link 87 via the wire end 103, As a result, the seedling feeding device 28 operates intermittently in synchronization with the raising and lowering of the planting section 69, that is, the planting operation, and the seedlings are supplied in response to the planting speed and timing.

13 and 14 show an example of a transplanting device for four-row planting, and the two-row planting devices shown in FIGS. 2 to 12 are all from the seedling feeding device 27 to the planting section 69. In contrast to the one for row, in this example, the seedling feeding device 27, the hopper 63, the planting section 69, and their driving mechanism are added to both sides of the two-row planting device. That is, an auxiliary frame 70 extending outward is attached to the tip of the swing arm 74 of the planting portion 69 to add the planting portion 69 to the outer end, and the shaft 77 of the lever 76 is parallel to the auxiliary frame 70. The bracket lever 76a is additionally installed on each shaft 77.

Further, FIG. 14 shows the seedling feeding device 28 and the seedling feeder 31 of the seedling feeding device 27 which are extended in one row each on the left and right sides. In the apparatus having the structure shown in FIGS. The number of articles can be increased easily.
